CONCRETE CONSTRUCTION.

To all whom it may concern:

Be it known that I, JOHN E. GONZELMAN, a citizen of the United States,residing at the city of St. Louis, State of Missouri, have inventedcertain new and useful Improvements in Concrete Construction, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

This invention relates to concrete building structures and hasparticular reference to a construction in which concrete slabs and beamsare used for ceilings and floors, and are supported at their ends andcorners by uprights or columns.

In the construction of concrete buildings, it is essential that secureand durable jointures be made between the columns and the horizontalmembers of the structure or the beams and slabs.

It is the object of this invention to provide a structure of concretebuilding elements which cooperate and are interengaged to form a rigid,secure and lasting combination of elements.

It is also an object to provide a concrete building structure in whichthe general construction of the cooperating uprights and horizontalelements is generally improved in the manner to be hereinafter set forthand described.

With these objects in view, my construction will now be fully set forthand described, reference being had to the accompanying drawings, inwhich,

Figure 1 is a longitudinal section through an upright, and thecontiguous horizontal members, and Fig. 2 is a sectional view on line 11of Fig. 1.

Referring more particularly to the drawings, the superposed columns 1and 7 represent one of the vertical units in a number of series ofalined columns which are spanned by and support a floor and ceilingstructure hereinafter described. Said columns are alined in ordinaryusage, in parallel rows.

This application is a divisional application of my copendingapplication, Serial No. 471,431, filed January 9, 1909. I

The column 1 is formed with a base or cap 2 provided with a shoulder 3and the stud 4. Said stud 4 rests on stud 5 of a cap 6 formed aroundcolumn 7 thereby provid- Specification of Letters Patent.

Patented June 14, 1910.

Divided and this application filed April 29,

ing the latter with shoulder 8. hen column l rests on column 7, a groove9 is formed between shoulders 3 and 8 and around studs 1 and 5. Saidgroove is adapted to receive beams 10, each of which is or may beanchored to column 1 by rod 11, or a plurality of such rods, extendingfrom base 2 into each of said beams and to the column 7 by a rod 12, orplurality of such rods, extending from the cap 6 into each of saidbeams. Preferably, the rod or rods 11, which extend from the column 1into beam, or beams, 10 will overlap rod or rods 12 extending fromcolumn 7 into said beam or beams. As is evident, the beams are securedto the columns 1 and 7 at right angles to one another, thereby providingright angled recesses or sockets in the groove 9 for the insertion ofthe corners of slabs which form the floor and ceiling members. Or, saidfloor and ceiling members or slabs may be inserted in groove 9 and thebeams 10 cast or molded between said slabs.

It will be observed that each beam 10 overlaps the joint 13 betweencolumns 1 and 7, and that by reason thereof and because of the positionof such beam in the groove between shoulders 3 and 8 and on account ofthe bond between beam 10 and columns 1 and 7, respectively, formed bythe rods 11 and 12, that a very strong union between the several partsis produced.

Having thus described my said invention, what I claim and desire tosecure by Letters- Patent is:

1. A concrete construction, comprising, in combination, alined rows ofsupporting columns, caps located around the bodies of said columns, andstuds projecting thereabove, similarly but opposingly formed columnssuperposed above said first columns, so as to have downwardly projectedstuds resting on said upwardly projecting studs, beams extended betweenthe columns of said alined rows and formed to have their ends insertedbetween the opposing caps, and in abutment with both of said studsthereby forming sockets around said abutments, and

columns, and studs projecting thereabove, similarly but opposinglyformed columns superposed above said first columns, so as to havedownwardly projected studs resting on said upwardly projecting studs,beams extended between the columns of said alined rows and formed tohave their ends inserted between the opposing caps and in abutment withboth of said studs, thereby forming sockets around said abutments,vertical rods projected from said caps into said beams to secure thelatter in angular relation, and quadrangular slabs fitting between saidbeams and having their corners inserted between said caps and fitting insaid sockets.

3. A concrete construction, comprising, in combination, alined rows ofsupporting columns, caps located around the bodies of said columns, andstuds projecting thereabove,

similarly but opposingly formed columns superposed above said firstcolumns, so as to have downwardly projected studs resting on saidupwardly projecting studs, beams extended between the columns of saidalined rows and formed to have their ends inserted at right angles toone another between the opposing caps, and in abutment with both of saidstuds thereby forming sockets around said abutments, andrectangularslabs fitting between said beams and having their cornersinserted between said caps and fitting in said sockets.

In testimony whereof I have alfixed my signature in presence of twowitnesses.
